14Three times a year you are to celebrate a feast to Me. 15You are to keep the Feast of Unleavened Bread as I commanded you: At the appointed time in the month of Abib you are to eat unleavened bread for seven days, because that was the month you came out of Egypt. No one may appear before Me empty-handed. 16You are also to keep the Feast of Harvest with the firstfruits of the produce from what you sow in the field. 17Three times a year all your males are to appear before the Lord GOD. 18You must not offer the blood of My sacrifices with anything leavened, nor may the fat of My feast remain until morning. 19Bring the best of the firstfruits of your soil to the house of the LORD your God.
